We spend lots of money on schools in the US and generally get pretty good outcomes. Our math scores leave something to be desired, but average reading scores are better than peer countries. There are plenty of exceptions, especially in poor neighborhoods, and chronic absenteeism is a real problem, but it's worth keeping sight of the fact that the vast majority of American schools are quite good.
Some examples:
